- Drive architectural decisions and establish patterns that support scalability, reliability, and developer productivity
- Collaborate closely with product, data, and partner teams to translate business requirements into robust technical solutions
- Provide technical leadership through design reviews, system discussions, and mentoring other engineers
- Contribute to engineering best practices, documentation, and long-term platform vision
